Terminal Services Session Broker (TS Session Broker) is a Terminal Services role service in Windows Server 2008 that supports session load balancing between terminal servers in a farm, and reconnection to an existing session in a load-balanced terminal server farm.

In order for the terminal server to join a farm in TS Session Broker, the terminal server must be able to communicate with the TS Session Broker server across the network. In addition, the computer account for the terminal server must be a member of the Session Directory Computers local group on the TS Session Broker server.

Note:  TS Session Broker was formerly called Terminal Services Session Directory.
